Kalibrointijärjestely

Kalibrointijärjestely refers to a systematic process used to establish the relationship between the values displayed by a measuring instrument and the corresponding known values of a measured quantity. This process ensures that the instrument provides accurate and reliable measurements. The term "järjestely" implies a structured arrangement or setup designed for calibration.

The core of a kalibrointijärjestely involves using traceable reference standards. These standards are instruments or artifacts with certified accuracy, whose own measurement uncertainty is known and documented. By comparing the readings of the instrument under test with the known values provided by the reference standard, any deviations can be identified.

A typical kalibrointijärjestely includes a set of steps. First, the instrument is prepared and allowed to stabilize. Then, measurements are taken at various points across its operational range. These points are chosen to adequately represent the instrument's performance. After the comparison, a calibration certificate is usually issued. This certificate details the results of the calibration, the conditions under which it was performed, the reference standards used, and the uncertainty associated with the calibration.

The purpose of a kalibrointijärjestely is to ensure that measurements are consistent, comparable, and meet regulatory or quality requirements. Regular calibration is crucial for maintaining the accuracy of measuring instruments over time, as factors like wear, environmental conditions, and aging can affect their performance.
